The application discloses a method for producing lithium manganese oxide as a positive material of lithium battery by dry mixing, which comprises the following steps: step one, uniformly mixing LiMnO4, manganese dioxide, nano niobium pentoxide, nano aluminum oxide, LiOH powder and boron trioxide at room temperature, and grinding to obtain a mixture; step two, stirring and mixing the mixture in step one and polyvinyl alcohol to obtain a powder mixture; step three, preparing an acidic solution by heating H2O and adding a mixture of prepared anhydrous ethanol and concentrated hydrochloric acid, and stirring to obtain the acidic solution; step four, taking part of the acidic solution and adding to the powder mixture in step two to obtain a suspension; step five, adding the remaining acidic solution into the suspension in step four, and heating to react in a sealed environment; after the reaction is completed, cooling the reaction product to obtain a crystal coated with emulsified glue; step six, sintering and screening the crystal in step five; and step seven, removing iron from the screened material to obtain a product.

This utility model discloses a wheat moistening device for flour processing, including a U-shaped frame. Two baffles are hinged to the outer wall of the U-shaped frame, and rubber sealing strips are fixedly embedded in the outer walls of both baffles. An equipment frame is fixedly connected to the outer wall of the U-shaped frame, and a first motor is fixedly connected to the inner wall of the equipment frame. A rotating frame is fixedly connected to the outer wall of the output shaft of the first motor, and a rubber hose is fixedly connected to the outer wall of the rotating frame. This utility model achieves uniform moistening of wheat by driving the rotating frame and stainless steel mesh frame to rotate through the first motor, avoiding uneven water penetration. By setting a stirring rod driven by a second motor, wheat and water are dynamically mixed, further improving the uniformity of moistening and preventing localized insufficient moistening or excessive water absorption. The rotating frame can be reset to an opening-down position, working with the stainless steel mesh frame to drain excess water quickly, improving moistening efficiency and reducing moisture residue.

The application relates to the field of road construction materials, and particularly discloses a road base mixture based on construction waste recycled aggregate and a preparation method thereof, the road base mixture is prepared from the following raw materials in parts by weight: recycled aggregate 80-100 parts, cement 20-30 parts, mineral powder 10-20 parts, fly ash 5-10 parts, water 14-20 parts, anti-shrinkage stabilizer 2-5 parts and reinforcing material 2-6 parts; and the preparation method comprises the following steps: S1, uniformly mixing and stirring the recycled aggregate, the cement, the mineral powder and the fly ash to obtain initial mixture; and S2, uniformly mixing and stirring water, the anti-shrinkage stabilizer and the reinforcing agent in the initial mixture to obtain finished mixture; the road base mixture has the advantages of high strength and good durability.

The embodiment of the application discloses a cooking method and device, a cooking equipment, a storage medium and a program product, wherein the method comprises: in a first constant temperature stage of a water absorption stage, controlling a heating assembly to maintain the temperature of food materials in a cooking cavity in a first temperature range within a first time range; the first time range and / or the first temperature range is an environmental condition for destroying the seed coat structure of coarse grains; in a cooling stage of the water absorption stage, the temperature of the food materials is cooled from the first temperature range to a second temperature range; the upper limit value of the second temperature range is less than the lower limit value of the first temperature range; in a second constant temperature stage of the water absorption stage, the pressure of the cooking cavity is changed through a ventilation assembly in the cooking cavity to promote water absorption of the food materials; in a curing stage after the water absorption stage, the food materials are cured through the control of the heating assembly to promote rapid cooking and curing.
